- Regular meeting
Zoom2 : https://zoom.us/j/6676627462
General announcement
- O4a run will start from 24th May
- 4 weeks run it will finish 21st June
- Mostly onsite and Mitaka member will have a shift for observation
- Not disagree that offsite member come KAGRA during run
- CAL/DET week from 17th May -
- We will stop the interferometer update
- SEO budget to PEM is limiting
- KAGRA visiting plan
- If you want to visit Kamioka, please contact to Yokozawa

General issue
- Status
Sensitivity ~1.4 Mpc latest
- Commissioning work
- Manual alignment
- PR3 : We will sometimes perform manual alignment
- OMC : Check the control signals
- Tapping test and shaker injection
Washimi-san summarized the shaker/acoustic injectionswiki
- 30 min acoustic injection test with one frequency
- Data for noise subtraction
- Glitch investigation
- ITMY suspension glitch
- Try to install the IR/GR filter in front of oplev QPD
- IPC glitch
It sometimes happened that the time series sometimes jump during observation example(klog24930)
- ITMY suspension glitch
- Lock loss investigation
- Ongoing
- Silent run
- Keep the interferometer when no CAL/DET/PEM activities
- Summary page update for O4a
- Ongoing
- Manual alignment
出張PEM injection (planning form)
Jurnal paper issue
- Micro seismic analysis (Hoshino)
- Submit to CPC soon
- Acoustic reverberation time paper (Washimi+)
- Suspend
- Re-measurement before O4?
- Tonga GIF paper
- Referee comments
Preparation for O4
- Environment will be fixed
- Temperature became lower due to no human activity inside the experimental area(?)
- Finalize the PEM installation
- Accelerometer to C chamber and TMS table (Maybe postpone after O4a, lower priority)
- Microphone to C chamber (Maybe postpone after O4a, lower priority)
- Investigation of the PEM injection
- Magnetic injection
- After O4a?
- Magnetic injection
- Voltmeter preparation
- AC power monitor installation
- DC power monitor installation
- After O4
- RF monitor with mokugo
- Tiltmeter
- RI detector
- Newtonian noise
- Discussion with DET members
